SCOM infrastructure capacity
I have a SCOM infrastructure deployed in my company running on 1 RMS, 3 MS servers, a separate dedicated SQL Server hosting the operational database and datawarehouse serving a few thousands agents. Now I would like to make some reports on the infrastructure to allow me to have an insight on the capacity of the infrastructure to be able to answer the following questions: how much of the capacity of the different servers and resources is used by SCOM ? Am I oversized for the moment ? How much agents can I accept without needing to add infrastructure components Trending on the used resources; when is my infrastructure on the most pressure ? By what (console users, which managament pack bjects, which agent ?) Which performance counters on the RMS, MS, SQL Server, Database, ... are the most significant to use for keeping an eye on the SCOM infrastructure itself ? RolandRoland

Mostly SCOM monitors itself. The rest is tuning. A good series of articles what you need to look at is here: http://www.systemcentercentral.com/BlogDetails/tabid/143/IndexId/61060/Default.aspx. Predicting how many agents you can still add is a really hard as the performance need seems to exponantially grow with the number of agents and management packs. What i don't like about ur setup is, is having the SQL db's on 1 server. i'd expect you'd run into trouble with several thousands of agents sooner or later. Then again if it works fine...

Nice link...thx Rob. Also, it depends on the hardware u r running everything on. I have ~700 servers being monitored quite comfortably from a single SCOM box (yes the SQL runs there too)....but it is a fairly hefty blade. I'd say ATM it is about 30% capacity. I know it's far from ideal, but it works and saves $$ according to the management! One thing I have avoided from experience are the really old Management Packs that are still available on the MS site. they just ruin performance. John Bradshaw
